"smooth, no vibrations, pulls without trouble from standstill up to 5000 and more revs, no exhaust popping, and it improves daily, probably due to the" Interesting. All this applies to my absolutely non-manipulated V7 Stone for two years now without restraint.

Let's keep in mind that Harry has an open airbox and mufflers and so his wasn't running so smooth before.I hope it actually does help and continues to, but keep an eye on the oil for dilution just in case.
Just put a pair on my 16 V7ii, after guttng the cats . The surge @ cold idle is gone (it would surge so bad on cold day it would flame out) , much better low & mid range performance . That was my main goal . Only 160mi. so far so milage haven't been sused out . Initially very satisfied . Taking off from dead stop is night & day improvement. Previously engine felt like it had no flywheel,if ya didn't slip clutch a bit it would fall on its face then cough & surge when it didn't stall! Dealer said latest map was installed & let me compare against his demo bike (cost me a box of donuts ) it was nearly identical to mine . Now ,no need to slip clutch a bit o throttle ,feed clutch out & it pulls nicely . As delivered fat ducs were set @ 1:00 o'clock position,I set it to 12:00 o'clock before install . the idea of plug n play appeals to me as I've a bit of warranty left. Providing dealer doesn't read this!! Happier rider

This came from factory tech just back from training ! Not surprising he also mentioned a number of other dealership personnel having issues w/reflashes done on the left coast. I appreciate all the 411 I can get.
Just before the warranty expired on my 2009 V7C,
